For the P4 DJI requires the mode switch to be in 'P' for VS to be able to take over flight controls. VS should inform you of this if you try to start tracking in any other flight mode. If you want to take over manually you can change to any other flight mode, just like before.

If you want to stay in 'P' mode, you may find it convenient to click the C2 button, which also cancels tracking.

I believe obstacle avoidance will not work when VS is being used and you are in 'P' mode, although we don't have a P4 to test that with. It looks like DJI has added support for this behaviour in their latest firmware/SDK, so we should add that capability in a future release.

Thanks. Sound good. So, obstacle avoidance and vision positioning system are working through theSDK. Great.

Now, does the Vertical tracking work if the P4 is in the Sport Mode, middle position of the mode switch? If you say that Vertical only works in the P position, I'd assume that doesn't work in the Sport Mode.

Tracking in the Sport Mode would be limited to following more rapidly moving things heading straightahead such as a car, motor cycle, etc. It would not track something moving rapidly from right to left, etc.

Control response with Phantom 4 on Ipad mini 2. Flew with Vertical Pro for the first time today. The control response was way to high. Would use stick for forward or aft or left or right and get no response and then get large 2 or 3 foot movement. This is response similar to what I got with velocitycontrol some months back. When I got response, the craft was jerking and then moving rapidly. At one point, ended up backing up into a fixed object. That's my first crash with the Phantom 4. Wasn't planning on doing that.

For info, I had flown immediately prior to this using the DJI Go App. Control was smooth and predictable. I had no problem there.

When I switched to Vertical, I got no control response and then over control.

Is there a place where I can adjust the setting on this? I would assume the control functions in the GoApp are ok because it flew smoothly using that.

The Vertical tracking app is easier to use and more versatile than the DJI go app. I'd like to be able to use it. Right now, I'm hesitant to do that.

Hi. I just downloaded Studio Pro and want to confirm the use of the mode switch on the Phantom 4.

What is the correct mode switch position for use with tracking with Vertical. Is it still switch to the rear for Vertical and then forward to P to disengage?

If you want to interrupt Vertical and take over manually, which mode switch position to you select.Is it still the "P" position?

I'm asking because the mode selection on the P3 and P4 is different. The middle position on the P4 is the sport mode.

Just for note, it is easier to halt tracking using the mode switch than tapping the display. That's thereason for the question.

And does the obstacle avoidance feature and the optical positioning system of the Phantom 4 still work when Vertical is being used?

Great that you have it up for the Phantom 4. Just want to get clarification on the operation with theP4.

Thanks.
